Abstract

Ultra-thin gate dielectrics processed by remote plasma nitridation (RPN) of N₂O-grown oxides subsequently followed by NO RTA treatment (N₂O+RPN+NO process) are reported for the first time as a means to extend the reliability scaling limit of SiO₂- / oxynitride-based gate dielectrics. These films show superior interface properties, significantly reduced leakage current, and improved reliability compared to other gate dielectrics of similar thickness (∼1.4 nm) fabricated by different processes.
